ELastic credentials not working for Elasticsearch Endpoints of elastic cloud deployement

Hi,
I am using free trial of Elastic cloud for a POC purpose.
I have created one test-observability-v1 deployment.
I have got ES endpoints, Kibana end points and APM end points affet deployement.
Also there one excel sheet for credentials. That excel contains username: elastic and a password with random characters.
When I hit the elasticsearhc endpoint in the browser, it asks for credentials
I am putting those credentials, bit not working.
Can someone help me on this?
Even I tried to reset that password and got new credentials from the reset link Still not working?
Am I doing anything wrong?

regards,
Sunil.
